This first ones deal....Don't they always put together the very first half dozen or so cars by hand, or specially built, nothing real "majorly" different, but just to get them out there for this type of thing?....They may be the first ones that like go to the top of the food chain, but it's done differently than how the cars will be built for "production"?....

...Just sayin' may be a time lag between the "first" ones and the rest...dunno for sure...
